Hi I want make a program for concatened matrix for example i want to obtain it:   How make a program for this ? In this example , matrix 3x3 in final application matrix nx3      

I have a worksheet that perfectly worked without units, but when I try to insert units RKfixed says that there are still units although I believe I stripped them all. Would someone be so kind to check what I did overlook?

Hello, When I try to move equations on the page to make page breaks come in convenient positions, everything goes haywire in Prime 5.  If I select a group of equations and (say) try to align the first one with the top of a page, sometimes that works, and sometimes it doesn't go where I drop it, but almost invariably some of the unselected equations on the page also move.  It makes it impossible to get everything simultaneously in a nice position. What's going on and how can I fix it? Thanks. Neil

Hi,I need your help in solving the following problem - Say, i have a main program worksheet ( Say A.xmcd ) where i have my inputs . Now my function ( set of calculations) is in another sheet ( Say B.xmcd )..Now i need to pass the inputs from A.xcmd to B.xcmd and receive the ouput from B to A .Say we have a very simple program in A.xcmdinputx= 3Functionf=cube (x)B.xcmdx1=xvalue = x1*x1*x1return(value)The above stated are not exactly the syntax but a pseudo code .How do i link A nd B from A ???

Hello folks,   I have an Excel sheet in which caloric properties for real gas are calculated. One of the values is only delivered when a VB code is executed in Excel. I strongly suspect that these are in a data map of sorts which is what I'm after. Since I can't access this table (the guy who created this sheet has left long since) I'd like to "push" the appropiate button in Excel from a Mathcad loop repeatedly and read out the data in a specific cell. Does anybody know whether this is feasible?   Raiko

please see attached file. i am trying to use the MINIMIZE function to find both the minimum value of the absolute function and the corresponding variable. as a result this variable would be a function of the remaining variable(s). i tried this with the ROOT function and it works. not sure why it would not work for MINIMIZE function. any help is very appreciated. thanks!

Hello Friends, I want to know the solution of the given below equation using Mathcad Prime 3.1. In above equation, two variable i.e. Phi. & Zeta is given but need to find out Psi. There is a figure given for reference which tells the relation in these variable as attache herein post.   Can anyone tell me how to calculate Psi using the given references and also if I need to plot it, then how can it be achived.   Thanks, Yogesh

I have been looking through the license information and contacted support, but neither gave me the specific answer to my question: Does the one year limitation for the student version extend to the Prime 5 product only or include MCAD 15 (050) as well? I even looked at the license file but couldn't decipher my answer from it. A little background: I had a previous student version (045) installed and on disc but lost the disc and the computer wiped. So with some time, and need, remaining on my student eligibility, decided to purchase 15 again (I don't much care for the Primes). I understood the license time limitation but would have enjoyed keeping 15 for home use. Again, it isn’t clear that when the prime 5 license expires that it takes the 15 one down with it. Maybe I should consider SMath when a year passes/eligibility is gone?

Why can't MathCAD solve this equation? It obviously works after simplifying it manually first as shown in the last step. But how can i get MathCAD to do it in the previous step?

I need to sum all elements of an array.  Is there a function that does this?

I am trying to invert a matrix using the variable names already declared.  I can invert the matrix if I manually enter the values of the variables, but not using the variable names.   I am obviously missing something and would be grateful for any guidance towards resolving the issue.   I attach the entire worksheet but I am only interested in comments on step 5 where the matrix manipulation appears.  I have left notes on the draft section of the page to show what the variable values are and what the problem is.   Kind regards and New Year's greetings to all.

First of all a happy prosperous and especially healthy 2019 to all! I have apparently a misunderstanding when to use indexing versus vectorisation. In the attached worksheet indexing works but vectorisation doesn't. Could someone help me out with this because I seem to be lost. Best regards, Filip

Happy new 2019 year with Mathcad 15 and Mathcad Prime too! I suggest the Mathcad users to raise a glass of wine on New Year's Eve, but not in the traditional way, but in a new way: to finish the animation shown below - pour wine into a glass and tilt the glass, showing the third projection!  

Dear all,I want to remove the straight line coming in the x-axis at the point -0.3in my attached plot.Please go through the attached plot.Thanks.

Hi all  I am doing a calculation of RLC circuit in MathCAD, but I am facing to a problem with usage of "i" ( notation of complex number) as shown bellow: Please help me to treat this .    Best regards,  

Hello! Is there any way to create the matrix "K" automatically? And put free expressions in the other matrix called "B"?    

how to plot graph from table or from excel in Mathcad ?

Prime 5.0 Electric Circuit  When L=1 my Mathcad sheet shows no error. When L=2 the sheet has an error.   I want to know the reason of my error.      

I'm not sure what's going on here.  I'm reading in a file and trying to get Mathcad 4.0 to add units to a column.  But it's not working as planned.  Tried a few different variations but always get the same issue.  What am I doing wrong?  

Hi Friends,   I am trying to write a formula for evaluating some conditional statement. I have an old pdf of that Mathcad sheet where all these calculation had been done but unfortunately I do not have this file with me. Can anyone tell me how can I combine return statement with if statement as shown in attached image.    This is also done in Mathcad but do not know the version. I am now using Mathcad prime 3.1 to do the same thing. I can use IF statement with else function here to get the desired output but first preference to write the formula in a similar way as shown in figure attached.   Thanks

Is there anyone converting my file mcdx to Xmcd or mcd?

Hello everyone. how to open a Worksheet file of mathcad prime 5 in Mathcad 15 ?

I am in school and trying to work through this example in the book. It all works out except the Theoretical Flow Rate which the book specifies as 15.3 GPM. From a little research I believe the issue is with how MathCad defines rpm but I can not figure it out.  Any help would be greatly appreciated, Frank
